锌浸出渣浮选银的高效药剂工业试验研究

Industrial Test Study on Effective Reagent for Silver Flotation in Zinc Leaching Residue

主要阐述了某湿法炼锌浮选回收银过程中应用一种新型高效浮选银药剂替代原丁胺黑药的工业对比试验,探讨了该药剂相比黑药的优势点,最经济的用药量,药剂组合尝试及解决了生产中出现的问题,提出了银浮选系统指标的控制方向。在不改动现有工艺基础上银回收率可以提高8.25%,在该冶炼厂搬迁工艺升级后,进一步跟踪取样试验,银回收率仍取得提高9.87%良好效果。

This article mainly elaborates on the industrial contrast test of using a new high-efficiency flotation silver reagent to replace the original butylamine black agent in the silver flotation recovery of a certain zinc hydrometallurgical process,makes a discussion of the advantages of this reagent compared to black agent,the most economical dosage of the reagent,attempts to combine the reagents,and solves the problems that arise in production,and proposes the control direction of silver flotation system indicators.On the basis of not changing the existing process,the silver recovery rate can be increased by 8.25%.After the relocation of the smelter and and process upgrading,further tracking sampling test showed that the silver recovery rate still achieved a good effect of increasing by 9.87%.
